Specification of Letters Patent.

Patented Apr. 191.1. Renewed September 23, 1910. Serial No. 583,501.

To (all whom it may concern:

lie it known that. 1, James \V. Snannn, a citizen of the United States, residing at El laso, in the county of El lnso, State of Texas, have invented certain new and useful Improvements in Feeddtcgulatois; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use same.

This invention relates to devices employed for feeding material from rewptacles, more particularly to devices of this character wherein dry, powdered or otherwise finely divided material is required to be finely and uniformly distributed;

The improved device is designed more particularly for use in connection with the crusher or storage bins of ore machinery, but which may be employed in connection with various machines in which finely divided material is stored and from which it is to be delivered to crushing or separating machines, and for the purpose of illustration the improved device is shown applied to a conventional bin for the storage of pulverized ores, but it will be understood that the invention is not necessarily limited to use in connection with any specific storage structure.

The invention consists in certain novel features of construction as hereafter shown and described and then specifically pointed out in the claims; and, in the drawings illusstrative of the preferred embodiment of the invention, Figure 1 is a side elevation, partly in section, of the improved device, applied. Fig. 2 is a plan view of the same with the bin in section on the line 2-2 of Fig. 1, and with the gate also partly in section. Fig. 3 is a detail sectional view on the line 33 of Fig. 1.

The improved device comprises a relatively short spout formed with vertical sides 10-11 and a bottom 12, the bottom being shorter than the sides, as shown in Fig. 1. The spout 1011-12 is inclined as shown, and connected to one of the side walls of a storage bin, represented at 14. All of the parts of the improved device are of plate metal, and the sides 1112 of the spout are connected to the bin by suitable angle-irons 1314, the lower ends of the angle-irons 1314 extending below the bottom of the spout, as shown, the object to be hereafter explained.

Fitting around the bottom and the sides of the spout is a relatively shallow chute comprising a flat inclined bottom 15 and vertical sides ItF-lT, the bottom 15 extending beneath the relatively short bottom 12 of the spout and the sides 1(3--l7 bearing against the vertical sides 10-l1 of the spout. Connected to the side 10 of the spout are guide blocks 18, while similar guide blocks it) are connected to the side 11, the longitudinal planes of the blocks corre sponding to the longitudinal plane of the spout, or in parallel relations to the bottom 15 of the chute. The vertical sides l617 of the chute are provided with longitudinal guideways or slots indicated at 20, and through which the blocks 18 19 extend, as shown. 3y this means the chute is maintained in position relative to the spout, while at the same time movable longitudinally thereof within the range of the slots. The chute is thus maintained in its parallel relation to the spout, while at the same time is free to be moved in longitudinal alinement therewith, as will be understood.

Connected to the depending portions of the L-ine1nbers 131-l are bearings ll-22, and mounted for rotation through these bearings is a shaft 28 having means, such as a belt pulley 24C, for imparting rotary motion thereto. Connected to the shaft 23, preferably midway between the bearings 2122, is an eccentric 25, and fitting over this eccentric is an eccentric head 26, the latter being riveted or otherwise secured as shown at 27 to a resilient strap 28. The forward end of the strap 28 is connected at 29 to the underface of the bottom 15 of the chute. By this simple arrangement it will be obvious that when the shaft 23 is rotated the eccentric 25 will operate the strap 28 and thus impart a rapid vibratory or shaking motion to the chute.

Connected to the inner face of the for- Ward terminal of the vertical side 10 of the spout are spaced vertical guide members 30, While similar vertical guide members 31 are connected to the inner face of the side 11, and slidable at its ends between the guide members is a shut-off gate 34:, the lower edge of the gate being adapted tobe located above the upper face of the bottom 15 of the chute,

and thus eut-otl the [low of the material, it required.

Extending across the upper ends ot the vertical members 30""31 is a transverse member 85, the latter being secured rigidly to the members filth-I'll, as shown. 'lhena-mber 35 is provided centrally thereot with a thr 'aded aperture through which a threaded rod 36 operates, the rod extending downwardly and mounted tor rotation in spaced bearings 37-38 on the gate 34-. The rod 36 is provided with a hand wheel 35) to facilitate its operation. By this simpl ar rangement it will be obvious that by rotating the screw 36 by its wheel 35) the gate may be elevated and depressed as required. By this simple means the feed operating beneath the gate may be readily controlled to correspondingly control the lion of the material.

\Vith a device thus constructed, itv will be obvious that. the material may be fed from the bin at a uniform rate and the amount of the material which is caused to llow over the chute may be readily con trolled by sin'iplv manipulating the screw rod 36, and thus adjusting the gate to any 10(.]1til'0(l extent.

The improved device is simple in construction, can be readily attached Without material structural changes to storage bins of various kinds and to storage bins ein ployed for various purposes.

hat is claimed is 1. In a device of the class described, a spout having spaced vertical Sides and an inclined bottom with the sides extending in ad vani'c oi the bottom, blocks connected to said spaced sides, a feed chute comprising an inclined bottom operating beneath the in clined bottom of the spout and with vertical sides engaging the vertical sides of the spout, the sides of the chute being provided with longitudinal slots bearing over said blocks and supporting the chute for movem-ent longitudinally of the spout, and maintaining the chute in constant parallel relations to the spent, and means tor vibratil'ig said chute.

In a device of. the class described, a spout having spaced vertical sides and an inclined bottom with the sides extending in advance of: the bottom, blocks connected to said spaced sides, a feed chute comprising an inclined bottom operating beneath the inclined bottom of the spout and with vertical sides engaging the vertical sides of the spout, the sides of said chute being provided with longitudinal slots bearing over said blocks and supporting the chute for movement. longitudinally of the spout, and maintaining the chute in constant parallel relations to the. spent, a gate o 'ierat-ing between the extendingside portions of the spout and within the chute, means for adjusting said gate, and means for vibrating said chute.

In testimony whereof, I attix my signature, in presence of two Witnesses.
